- This invention relates to new and useful imgroveinents in fuel burners,

ne ohject of the invention is to provide an improved burner particularly adapted for atomizing fuel, and which may he constructand which are likely to loecome stopped up,

are obviated. By providing the passages on the outer surface of the plug, such passages ere fully exposed for cleaning and inspection when the plug is removed.

Another ohjeet of the invention is to provide a compact and simple structure erranged so that when the ti is removed the plug is carriecl thereby en the open enrl oi the edepterg or the supply tube, is exposefi end thus made free to ecwss,

A further object of the invention is to rovide a burner of the atomising type in w ich an ample storage chemloer is provi ierl conti uous tothe' tangential ducts, wherehy en 6 aoequate supply of fuel is provided for said due Still another object of the invention is to provicle e plu for a burner in which the fuel passages are lormerl in the outer surface so 35 as to either be cast or readily cut therein, thus making for quicker and cheaper production.

A construction designed to carry out the invention will be hereinafter descrhed together with other featuresol the invention.

The invention will be more readily understood froma reading of the following specification and by reference to the accompanying drawing in which an example of the invention is shown, and wherein:

Figure 1 is a longitudinal sectional view es, whereby such,

ln the drewing the numerel l0 uesignates a c lindrical burner heed which is formed wit a tlishecl face .or forward endl 11 and has an internally screw=threade& socket 12 at its inner or rear end, The socket terminates at on internal annular fienge 13, out hetweeu this flange and the front wall of the head is an annular storage chamher 14:.

The reduced screw-threaderl pin 15 oil on edia ter 16 is serewedi into the seelret 5 .2; against the fiengel3. The aclaxpter hes on. internal screw-threade socket l whieli receives the end of a fuel supply tube 18. @il,

as, or other fuel, or a'mixture of fuels is so through the tuhe 18 to the hurrieso it would he within the scope oi the invention to screw the tube 18directly into the heacl I 10, and thus eliminate the arlapter. lt will he noted that the adapter has e bore 19 of substantially the some diameter as the tube, and .wlien'the heel is removed this here is exposes so that the tube may be readily cleanecl or blown out.

A plug-20 is formed with a circumferential collar 21 at its intermediate portion, and this collar is proviued with external screw threads 22 adapted to engage in threeais 23 provided in the flange 13. The plug has t till flat face 24st its forward end, and when said diameter so us to eject the plug is screwed into the flange, this face cu gages and forms a. fiuidtight seat with the inner surface or fiat face 25 of the trout wait of the burner heard 19.

The rear cud oi the plug is provided with e diemetricoi groove or recess 26 for receiv-- ing a screw driver or other tooi, vvherehy ssid plug may be screwed into or removed from the head. ()u diemetriceiiy opposite sides of the piug longitudinal ducts or grooves 93'? extend forwurdiy from the ends of the groove 26. At their iorwurd ends the ducts are provided with curved deflectors 28, It is pointed out that the ducts could he milled and the miiiing toot vvouid finish up the ducts with the curved deflectors 28. in this Way the plug mey he inexpensively produced. When the plug is screwed into the head, the deflectors extend into the urmuisr chamber 1 and consequently fuel received "from the tube 19 end curried along the ducts is deflected or spread outwerdiy into the chamber M.

The foru erd sud of the piug is provided with u circuiur churuher or recess 29, end e piureiity of ducts 3t) extend tuugeutiuiiy from this recess to the outer surface or -the plug, By this srreugezueutfuei entering the recess from the storuge chamber it through the ducts 30 Wiii he. cuus-ed to-whiri in said recess, and the turhuieuce thus set up Wiii promote atomization and comhustiou. A substantially semi-spherical sump 311 is formed in the front wait of the heed and ceutreiiy iocuted so us to register with recess 29. It is preferable to moire the hose diameter of the sump the us the diam eter of the recess so thet the joint hetrveeu these ports wiii he flush ho ohu ructiou ofiered to u iortvsrd movement ot the fuel fluid. A port 32 extends uuisiiy through the head from the sump, and is of o reduced stream or jet.

It is pointed out that the ducts 2? iii the plug 26 provide tree and unobstructed pesssges for the fuel fluid The eunuier chore her 14 is of such size and c'upscity us-to st cit times store sutlicieut :iuei fluid to prevent starvation of the ports 30, recess 29 cud sump 31. When the head is screwed ofi of the pin 15 the plug is carried with the head, cud the bore 19 is immediuteiy expose-d, it is not necessary to unscrew sdditiouui ports to secure such access. When the piug so is reimoved from the head the ducts 27, recess 29,

and ports 30 are oh exposed, sud they he easily cleaned or inspected. This is perticuiariy advantageous when compared with those plugs in which the ports or ducts ere bored or drilled through the plug,
